Abstract

The invention provides a method, an apparatus and a system 1 for operating a rotating electric machine. The method has the following steps: defining (S01) a rotor position angle reference value of a rotor of the rotating electric machine (REM); determining (S02) a first rotor position angle measured value of the rotor during operation in the case of essentially a first speed of the rotor by means of a rotor position detection device (REE) of the rotating electric machine (REM); determining (S03) a second rotor position angle measured value of the rotor during operation in the case of essentially a second speed of the rotor by means of the rotor position detection device (REE) of the rotating electric machine (REM), wherein the second speed of the rotor differs from the first speed of the rotor; defining (S04) a first angular offset as the difference between the first rotor position angle measured value and the rotor position angle reference value; defining (S05) a second angular offset as the difference between the second rotor position angle measured value and the rotor position angle reference value; and calculating (S06) a signal delay of the rotor position detection device (REE…
